This report details the findings from an exploratory research study conducted by the Research and Evaluation Department at the Museum of Science, Boston about this exhibition, which came to be known as Provocative Questions (PQ). This investigation was guided by the following questions: 1. Will visitors engage in socio-scientific argumentation in an un-facilitated exhibit space, and are they aware that they are doing so? 2. How do the un-facilitated exhibits impact visitors’ socio-scientific argumentation skills? For the exploratory research study, visitors were cued to use the exhibits and
